Parallel Generation and Acquisition

[martinmistere]

Hi.i'm using cRIO with NI 9215 and 9263 modules.

I want to know if it is possible to make in a single VI generation and acquisition in parallel using a FIFO local for the generation and a FIFO DMA for the acquisition.

I've seen a lot of posts of other people but as i've understood nobody has made it to work. Ca you give me some suggests?

Tnx a lot.

Hello martinmistere,

I am not sure if I have well understood your problem: have you already taken a look at the following documents?

Using DMA FIFO to Develop High-Speed Data Acquistion Applications for Reconfigurable I/O DevicesUsin...

DMA Improves LabVIEW FPGA 8.0 Throughput by 20X

They explain how to use DMA transfer method into a FIFO architecture. Also, what do you mean with "FIFO local" ? I guess it could be the local FPGA onboard memory.

Hope this helps

best regards,

Fabio

Martin,

Please take a look at this example posted on DevZone.
